The news production of the new media platform is different from the past. While reading news, the audience will also read the comments. From the perspective of reception theory, news itself is the first text, while comments are the second text. The microblog short comments are the reflection of the audience′s rethinking and interpretation after receiving news, which are manifested as the supplement, expansion, resistance and explanation of the news text. Based on the audience′s own horizon of expectation, they create the second text and constitute a complete news receiving process with the news ontology. This process extends the vitality of news production and expands the cognitive boundary and field of vision of the audience, which enables the meaning of news to be fully explained, extended and expressed.
